CABLE GOINVEYER.

Patented Nov. 18, 1919.

Application filed March 6, 1918. Serial No. 220,793.

To all whom it may concern:

Be it known that I, CHARLES G. DELLnN- BAGH, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Cable Conveyers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements 1n conveyers of the class in which each mechanism has an endless cable with spaced flights secured to the cable by attachment devices which also engage the teeth of the sprocket Wheels that guide and propel the conveyor. The object of the invention is to provide an attachment for each flight which can be gripped to the cable so securely as to prevent any movement, transversely or long1- tudinally, of the attachment or of any of its parts relatively to the cable, and which will not involve any deforming of the cable or throwing it or any of its strands into abnormal position The devices by which I attain this object are fully set forth in the following specification, reference being had to the accompanying drawings in which Figure 1 is a fragmentary assembly view of such a conveyer cable showing the relation of two attachments to the cable and to each other.

Fig. 2 is an elevational view of such an attachment taken along a plane transverse of the cable.

Fig. 3 is a sectional view taken along the adapted to be engaged by the teeth of a driving sprocket wheel to propel the cable and to engage the materia in a conveyer trough to move said'material, in a manner well known in conveyer practice.

As shown, each of the attachments comprises two elements 3 and 4: adapted to meet, and to be separated, at a plane longitudinal of the cable and remote from its periphery. The element 3 is considerably smaller, as an entirety, than that indicated by 4. Each is cast integral with the half larger attachment part 4 is formed with a longitudinal groove 7 of a depth considerably greater than the diameter of the cable and of a width such that its walls fit tightly against all of the lower half of the cable surface, This element =l of the attachment is also formed with a groove 8 in the trans verse planes of the flight sections 6, 6; the depth of this groove being greater than that of the groove 7.

The smaller attachment element 3 has a longitudinal rib'or tongue 10 fitting snugly inthe groove 7 of the opposite element; the edge being concave to provide contact over all of the upper part of the surface of the cable.

The flight section 6 of the element 3 has a straight inner edge which is transverse to, but lies in the plane of, the edge of the tongue 10. The edge part, indicated by 9, serves as a tongue which can enter, and fits between the walls, of the groove 8- in the element 4:.

When the parts of the attachment are brought together and held in working position the tongues 9 and 1-0 fit in the grooves 8 and 7 respectively- At 5, 5 there are bolts which pass through the attachment elements 3 and 4, and by which-they are drawn powerfully together. When they are so drawn the tongue 10 is caused to bear against the cable and the tongue 9 is forced into the groove 8. v

The flight sections 6, 6 are constantly subjected to twisting and torsional strains; and as it is not practicable to have the bolts fitted in their apertures with perfect tightness these strains tend to cause slippings or shifting of the attachment elements upon each other and in relation to the cable. I prevent this by utilizing the edge part at 9 of a flight section ,6 as a locking tongue, and hold the two disk attachments against displacement preventing them from slipping transversely or longituinally, relatively to each other or to the cable.

It will be seen that I do not bend or crimp the cable; nor do I pass anything through it nor in any way deform it. The

slippage of the flight on a cable from one position to another, lon 'itudinally, I have found to be due to the slight relative movements of the elements of the clamps, these movements being caused by strains, first in one direction and then in the other, from the loads on the flight sections 6. By my improvement I hold the two flight sections of each element rigidly in their predeter mined plane, and utilize the edge part 9 of one of them as a tongue to lock the two elements 3 and 4: of the attachment against relative movement.

What I claim as new and desire to secure by Letters Patent is- In a cable conveyor, the combination with the cable of the larger attachment element plane of the flight section and intersecting the cable groove, the smaller attachment element 3 with a longitudinal tongue adapted to fit in the cable groove in the larger element and having the integrally formed flight section with its inner edge part 9 adapted to fit as a tongue in the aforesaid transverse groove, and the bolts for clamping the elements together.

In testimony whereof, I afiix my signature in presence of two witnesses.
